Abstract

A front structure of a vehicle body includes a first bumper reinforcement extending in a lateral direction of the vehicle body. A second bumper reinforcement extends in the lateral direction of the vehicle body below the first bumper reinforcement. Two first crash boxes are coupled to the two ends of the first bumper reinforcement. Two second crash boxes are coupled to the two ends of the second bumper reinforcement. Two vertical posts are coupled to the rear ends of the first and second crash boxes. Two side frames are coupled to the two vertical posts opposite to the first crash boxes. Two lower members are coupled to the two vertical posts opposite to the second crash boxes. A lower support member couples the second crash boxes to each other and forms a lower portion of a radiator support.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a front structure of a vehicle body that absorbs collision load applied from the front of a vehicle body.[0002]Japanese Laid-Open Patent Publication No. 2009-40187 describes a bumper device that is one example of a front structure of a vehicle body. As shown in FIG. 9, the bumper device 100 includes a first bumper reinforcement 101 and a second bumper reinforcement 102, which extend in the lateral direction of a vehicle body. First crash boxes 103 (only one shown in the drawing), which extend in the longitudinal direction of the vehicle body, are coupled to the two ends of the first bumper reinforcement 101. Second crash boxes 104 (only one shown in the drawing), which extend in the longitudinal direction of the vehicle body, are coupled to the two ends of the second bumper reinforcement 102. A side member 105, which forms a portion of the vehicle body, is coupled to the rear end of each first crash box 103 with a sid...
